In nutrition, diet is the sum of food consumed by a person or other organism. The word diet often implies the use of specific intake of nutrition for health or weight-management reasons (with the two often being related). Although humans are omnivores, each culture and each person holds some food preferences or some food taboos. This may be due to personal tastes or ethical reasons. Individual dietary choices may be more or less healthy.
Complete nutrition requires ingestion and absorption of vitamins, minerals, essential amino acids from protein and essential fatty acids from fat-containing food, also food energy in the form of carbohydrate, protein, and fat. Dietary habits and choices play a significant role in the quality of life, health and longevity.
There are thousands of diets. Some are for losing weight, while others are for gaining weight, lowering cholesterol, living a long and healthful life, and many other reasons.
A diet is best described as a fixed plan of eating and drinking where the type and amount of food are planned out in order to achieve weight loss or follow a particular lifestyle.
Here are some diets that are popular in the community
1. Mediterranean diet
The emphasis is on lots of plant foods, fresh fruits as dessert, beans, nuts, whole grains, seeds, olive oil as the main source of dietary fats. Cheese and yogurts are the main dairy foods. The diet also includes moderate amounts of fish and poultry, up to about four eggs per week, small amounts of red meat, and low to moderate amounts of wine.
2. Raw food diet
The raw food diet, or raw foodism, involves consuming foods and drinks that are not processed, are completely plant-based, and ideally organic.
3. Vegan diet
Veganism is more of a way of life and a philosophy than a diet. A vegan does not eat anything that is animal-based, including eggs, dairy, and honey. Vegans do not usually adopt veganism just for health reasons, but also for environmental, ethical, and compassionate reasons.
4. Vegetarian diet
The majority of vegetarians are lacto-ovo vegetarians, in other words, they do not eat animal-based foods, except for eggs, dairy, and honey.
Studies over the last few years have shown that vegetarians have a lower body weight, suffer less from diseases, and typically have a longer life expectancy than people who eat meat.
5. Ketogenic diet
The ketogenic diet has been used for decades as a treatment for epilepsy and is also being explored for other uses. It involves reducing carbohydrate intake and upping fat intake. It sounds contrary to common sense, but it allows the body to burn fat as a fuel, rather than carbohydrates.
6. Atkins diet
The Atkins diet, or Atkins nutritional approach, focuses on controlling the levels of insulin in the body through a low-carbohydrate diet.
If people consume large amounts of refined carbohydrates, their insulin levels rise and fall rapidly. Rising insulin levels trigger the body to store energy from the food that is consumed, making it less likely that the body will use stored fat as a source of energy.
Therefore, people on the Atkins diet avoid carbohydrates but can eat as much protein and fat as they like.
Although popular for some time, the Atkins Diet comes with certain risks. Individuals considering the Atkins Diet should speak with their doctor.
A healthy diet may improve or maintain optimal health. In developed countries, affluence enables unconstrained caloric intake and possibly inappropriate food choices.
Health agencies recommend that people maintain a normal weight by limiting consumption of energy-dense foods and sugary drinks, eating plant-based food, limiting consumption of red and processed meat, and limiting alcohol intake.
The Dietary Guidelines for Americans is an evidence-based information source that policy makers and health professionals use to advise the general public about healthy nutrition.
Expert Panel: Everything You Need To Know About Nutrition! More diets than ever seem to offer you life-changing results—and have research to back them up. So which one is for you? Two of the best minds in muscle meet up to give you the lowdown!

What will you eat today? You have a world of choices, and a world of people ready to tell you why you’ve chosen wrong. It can be overwhelming, especially because sometimes it seems like your very life—or at least the life your six-pack, hard-earned muscle mass, or other aesthetic goal—is at stake. So where do you start? Start here!
In the second of our expert panel roundtable discussions, we invited Dr. Jacob Wilson and Dr. Robert Wildman to discuss the fundamentals of goal-based nutrition and how the scientific landscape is rapidly changing. They break down some of the rules that should guide trainees with a range of goals, from losing large quantities of fat, to chiseling off a couple percentage points. Then they discuss three increasingly popular dietary protocols—ketogenic diets, “if it fits your macros,” and intermittent fasting—from the perspective of fat-loss and muscle preservation.
